Trevor Warren enters his seventh season as the Green Bay women's soccer head coach in 2014. A former defender himself, Warren has the Phoenix coming off four of the best defensive seasons in school history.

During the 2013 season, Green Bay held opponents to a 1.12 goals scored per game average, posting five shutouts while also limiting its competition to 0 or 1 goals in 13 of its 17 matches. Helping on the defense, then-freshman Katie Schulz was named to the Horizon League All-Newcomer team, while teammate Hannah Kernen collected first team all-conference honors.

Green Bay surrendered one or zero goals in 14 of its 18 contests in 2011 and gave up just 16 goals through its first 17 matches. In 2010 the Phoenix allowed just 15 goals in 16 contests, tying a school record (1993) for the fewest goals allowed in a season. The team's 0.88 goals-against average was the third lowest in program history, as the Phoenix notched five shutouts on the year and allowed no more than a single goal in 14 of its 16 matches. For the team's stout defense, goalkeeper Maddie Drusch, then a junior, earned second team all-league honors. Drusch, who played all four years under Warren, finished her career as the school's all-time leader in goals-against average (1.20) and saves (386) and second in shutouts with 16.

In Warren's first season in 2008, Green Bay improved its winning percentage by over 30 percentage points to rank as one of the nation's most improved programs.

Warren's impression on the program in his inaugural year was to establish sound defense, which was apparent with the team's goals-against average. After registering a 2.51 goals-against average prior to Warren's arrival in 2007, Green Bay had a 1.36 GAA with four shutouts in 2008 and a 1.54 GAA the following year.

Warren was named the head coach of Green Bay's women's soccer program Jan. 17, 2008. Since that time, he has made sure members of his program are competitive on the field and successful in the classroom. Most recently the Phoenix posted a 3.24 team GPA during the fall 2012 semester. Also of note, former Phoenix standout Amanda Stinson earned a CoSIDA Academic All-District V selection in 2008-09.

Warren's position with the Phoenix is far from his first head coaching job. In 20 seasons as a collegiate coach, Warren has served as the head coach for two other collegiate programs and has appeared in four NCAA tournaments. He boasts a head coaching record of 103-38-7 in eight years at the NCAA Division II level at Mercyhurst and Lock Haven, starting the Lock Haven program from scratch.

At Lock Haven (Pa.) University, he led the Lady Eagles to a 44-25-3 record over the program's inaugural four seasons. Along the way, Lock Haven posted back-to-back regular season conference titles in 1996 and 1997. While at Mercyhurst (Pa.) College, he was the head coach of both the men's and women's soccer programs. As the head coach for the women, Warren guided the Lakers to the 1993 NCAA Division II Final Four and a quarterfinal appearance in the 1991 NCAA tournament while compiling a 59-13-4 mark.

Warren made the transition to Division I in 2002 when he began a three-year stint as an assistant coach for both the men's and women's soccer programs at the University of Portland. In his first season with the Pilots, Warren assisted former Olympic and national head coach Clive Charles and the women's program to its first-ever NCAA title. Warren also worked with two-time National Player of the Year, Christine Sinclair.

Following his time at Portland, Warren spent one season as an assistant at Northern Iowa prior to joining the Phoenix. He aided the Panthers in posting a 6-10-2 record in 2007. It was the team's second-best season in program history and matched the team's win total of the previous three seasons combined.

Warren, a United States Soccer Federation 'A' licensed coach, got his collegiate coaching start as a men's assistant coach with stints at SUNY Brockport and Gannon (Pa.) University.

No stranger to success at the club level as well, Warren spent nine seasons coaching club soccer in Oregon, including seven years with FC Portland before serving as the Director of Coaching with Southside Soccer Club in Portland, Ore., for two years. Under his watch, FC Portland claimed three state titles and a U-18 US Club Soccer national championship in 2003.

Warren also has an advanced national diploma from the National Soccer Coaches Association of America and an English Football Association coaching license. He has also coached at the Olympic Development level, serving as a staff coach for Pennsylvania West from 1988-97, Oregon from 2001-06 and the Region IV program from 2003-05.

Warren is a graduate of the University of Newcastle in England, where he received a B.E. in physical education in 1978.
